This week I told the remarkable story of PeaceJam, the Colorado-based non-profit that a down-and-out Denver artist was inspired to start after the Summer of Violence. From those unlikely beginnings, PeaceJam has grown to a powerhouse that includes thirteen Nobel Peace Prize laureates on its board and hosts activities around the globe, including the debut of a documentary on Archbishop Desmond Tutu in Monte Carlo early this month. As the fourth annual Clinton Global Initiative America comes to Denver this weekend, it's a good time to remember that hometown heroes can have an international impact, too.

On Sunday, June 22, the Bill, Hillary & Chelsea Clinton Foundation, founded by Chelsea Clinton in the wake of Hurricane Katrina, will partner with Concerts for Kids on a Day of Action. Led by Chelsea Clinton, who'll be speaking along with Governor John Hickenlooper, the Day of Action will mobilize hundreds of volunteers to complete service projects at six nonprofits across Denver, including the Boys & Girls Club, Food Bank of the Rockies, Mi Casa, Habitat for Humanity and Project CURE.

Then from June 23 through June 25, former president Bill Clinton, former Secretary of State and perhaps future presidential candidate Hillary Clinton, and Chelsea Clinton will host the Clinton Global Initiative, bringing leaders in business, government and civic ventures across the country to Denver for three days of discussion. Let's hope there's a spot at the table for PeaceJam.
